Background: Various recent studies have reported that exclusive right nostril breathing (RNB) and left nostril breathing (LNB) has an immediate and sustained effect under various medical conditions. In the present study, we evaluated the effect of short-term left nostril breathing on various sleep parameters in medical students. Methods: We hypothesized that the increase in vagal tone because of LNB can help in improving the quality of sleep. The baseline sleep quality was documented before the start of study in the case and the control group using the 'Pittsburgh Sleep Quality Index' (PSQI) questionnaire. A PSQI global score of more than 5 indicates poor sleep quality. The case group practiced LNB in a graduated manner for a period of 4 weeks. Thereafter, sleep quality was documented for both the groups using the PSQI questionnaire. Results: Practicing LNB significantly lowered all the seven component scores (p < 0.05) and the global PSQI score in the case group (p-value < 0.0001), suggesting that this practice effectively improved the sleep quality in the individuals of this group. Conclusions: Overall, this study suggested that exclusive LNB practice could serve as an important lifestyle modification that can be incorporated in the routine of medical students for improving their sleep quality.
